.I 008cm PATENT OFFICE l Claim.

This invention appertains to building blocks and tiles formed fromcementitious or similar material and more particularly to so-calledcinder blocks.

One of the primary objects of my invention is to provide a block or tilewhich can be readily broken by the builder on the job into various sizesof complete blocks or tiles, so that a desired of block or tile will behad to lit a particular space.

Another salient object of my invention is to provide a block or tilehaving pairs oi spaced transverse partition walls, the block or tilebeing adapted to be broken in between the Walls of the pairs oi walls toform a complete block having walls at each end, the pairs of walls beingspaced different distances apart, so that the block can be broken toform smaller blocks of varying sizes and combination of sizes.

A further important object of my invention is to provide a block ortile, which is so constructed that the same can be readily brokenlongitudinally to provide slabs for diierent purposes.

A still further object of my invention is to provide a tile or block ofthe above character, one that will be efficient in use, one which willbe easy to manufacture and one which can be placed upon the market at areasonable cost.

With these and other objects in view, the invention consists in thenovel arrangement, construction and formation of parts, as will behereinafter more specifically described, claimed and illustrated in theaccompanying drawing, in which- Flgure l is a top plan view of my tileor block.

'Figure 2 is a central longitudinal section through the same taken onthe line 2-2 of Figure l lookin in the direction of the arrows.

Figure 3 is a transverse section through the block or tile taken on theline 3 3 of Figure l looking in the direction of the arrows.

Figure l is a top plan view illustrating a slightly modified form of myimproved block.

Referring to the drawing in detail, wherein similar reference charactersdesignate the corresponding parts throughout the several Views, theletter A generally indicates my improved tile or block, which is adaptedto be formed on a con- '.fenticnal block molding machine. As shown, theblock or tile A comprises longitudinally extending sde walls 5 and S andend walls l and 8. The side walls 5 and S are connected at spaced pointsby pairs oi transversely extending partition walls or webs s, It' andiI. ese pairs of partition Walls S, It and II are spaced differentdistances apart relative to one another and to the end walls 'l and 8,for a purpose which will be later set forth.

If desired, the lower end of the block or tile can be closed by a bottomWall to reinforce the block or tile, and the bottom wall I2 is provided5 with openings I3. All of the Walls are so shaped as to facilitate theremoval of the block from the mold. It is tol be noted, however, thatthe space between the pairs oi walls is left open from the top of theblock to the bottom. 10

By forming the block 01 tile with the pairs of spaced partition walls`9, I 0 and I I, the block can be readily broken transversely by a trowelor similar instrument between the Walls or pairs of walls. This allowsthe breaking oii of a complete block having end Walls. Obviously, byhaving the pairs of Walls spaced different distances apart, varioussizes or blocks can be had, and a number of different combinations ofsizes can be formed.

The block is also adapted to be readily broken longitudinally so as toform building slabs and in order to facilitate such breaking, the pairso-f partition walls 9, I0 and I I are provided with notches I4 all ofwhich are in longitudinal alinement. Thus, a block or tile is weakenedat its longitudinal axis which allows the block to be broken in slabs.

While in Figures 1-3, inclusive, I have illustrated a particular form orblock or tile, it is to be understood that other sizes of blocks can bemade and inFigure 4 I have illustrated another form of my block. Thisform is generally indicated by the reference character B and as shown,the same embodies front and rear walls I5, I6 and end walls I'I and I9.The front and rear walls are connected by a single pair of spacedpartition Walls I9. In this particular instance, the pair of spacedpartition walls are located at a point equi-distant between the endwalls I1 and I8. 40

It is to be also noted that in this particular instance, the notches I4are eliminated from said transverse partition Walls.

From the foregoing description, it can be seen that I have provided ablock or tile of an exceptionally simple and durable construction, whichcan be readily broken at the sections to form blocks of desired size tot a particular space.'

Changes in details may be made Without departingfrom the spirit or thescope of this invention, but what I claim as new is:-

A blo-ck or tile comprising a hollow body including a pair of spaced,parallel, longitudinally extending side Walls and connecting end walls,pairs of partitioned Walls extending transversely across the body andconnecting said side Walls together, said pairs of partition Walls beingspaced different distances apart relative to one another and to the endWalls, the Walls of each pair of partition Walls being located in closeproximity to one another and forming an opening extending through thebody, said block being adapted to be broken in between the Walls of thepairs of partition Walls to form complete sections of diierent sizes,and each of said block sections being provided with bottom walls, all ofsaid partition Walls having break slots in their outer edges arrangedin'longitudinal alinernent, said break slots extending a materialdistance in said partition Walls whereby to facilitate the breaking ofthe block into longitudinal sections.
